The IRS is an interdisciplinary institute and welcomes guest researchers from a variety of disciplinary backgrounds. Since its foundation, the IRS has hosted geographers, political scientists, economists, sociologists, historians and scholars from planning science. Cooperation amongst guest researchers and IRS scholars (on lectures, publications and third-party funding applications for example) enhances the institute's research efforts and contributes to the institute's ongoing development.
At the IRS, guest researchers benefit from an excellent research infrastructure, and from the institute's close ties to universities and non-university research institutes in the Berlin-Brandenburg region. During their stay, guest researchers are invited to participate in and contribute to workshops and conferences held at the IRS. The institute can provide three fully equipped workspaces for guests.
